ASTM D2593-93(2014)

Standard Test Method for Butadiene Purity and Hydrocarbon Impurities by Gas Chromatography

SIGNIFICANCE AND USE
4.1 The trace hydrocarbon compounds listed can have an effect in the commercial use of butadiene. This test method is suitable for use in process quality control and in setting specifications.
SCOPE
1.1 This test method covers the determination of butadiene-1,3 purity and impurities such as propane, propylene, isobutane, n-butane, butene-1, isobutylene, propadiene, trans-butene-2, cis -butene-2, butadiene-1,2, pentadiene-1,4, and, methyl, dimethyl, ethyl, and vinyl acetylene in polymerization grade butadiene by gas chromatography. Impurities including butadiene dimer, carbonyls, inhibitor, and residue are measured by appropriate ASTM procedures and the results used to normalize the component distribution obtained by chromatography.  
Note 1: Other impurities present in commercial butadiene must be calibrated and analyzed. Other impurities were not tested in the cooperative work on this test method.
Note 2: This test method can be used to check for pentadiene-1,4 and other C5s instead of Test Method D1088.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.1 and 9.3.

3. Summary of Test Method
3.1 A representative sample is introduced into a gas-liquid partition column. The butadiene and other components are separated
as they are transported through the column by an inert carrier gas. Their presence in the effluent is measured by a detector and
recorded as a chromatogram. The chromatogram of the sample is interpreted by applying component attenuation and detector
response factors to the peak areas or peak heights and the relative concentration determined by relating individual peak response
to total peak response. Impurities including butadiene dimer, carbonyls, inhibitor, and residue are measured by appropriate ASTM
procedures and the results used to normalize the distribution obtained by gas chromatography.
